MicroRNAs (miRNAs) play critical roles in hepatocellular carcinoma (HCC). However, the expression and biological function of miR-345 in HCC remain unknown. The present study demonstrated that miR-345 expression was reduced in HCC tissues and cell lines. Decreased miR-345 expression was associated with unfavorable clinical features and poor prognosis. In vitro functional assays showed that miR-3...

A subset (gamma(2)) of late herpes simplex virus 1 genes depends on viral DNA synthesis for its expression. For optimal expression, a small number of these genes, exemplified by U(S)11, also requires two viral proteins, the alpha protein infected cell protein (ICP) 22 and the protein kinase U(L)13. Earlier we showed that U(L)13 and ICP22 mediate the stabilization of cdc2 and the replacement of ...

Aquaporin-4 (AQP4) is a water transport protein expressed in glial cell plasma membranes, including glial cell foot processes lining the blood-brain barrier. AQP4 deletion in mice reduces cytotoxic brain edema produced by different pathologies. To determine whether AQP4 is rate-limiting for brain water accumulation and whether altered AQP4 expression, as occurs in various pathologies, could hav...

Sambucus nigra (elder) are broadly used species to treat microbial infections. Thepotential antiviral activity and mechanism action of elder fruit (EF) in human epithelium cell(A549) cultures infected with H9N2 influenza virus were determined. The effect of variousconcentrations of EF on influenza virus replication was examined by using virus titration,quantitative real time RT-PCR, fusion and ...

We have used an in vitro nuclear run-off assay to measure the levels of transcription of specific herpes simplex virus genes at different times during a lytic infection. We analyzed the effects of inhibition of DNA replication and of defects in two herpes simplex virus regulatory proteins on the transcription of these genes. We present evidence that the transcription of the alpha ICP4 gene is n...

background: the rh antigens are expressed as parts of a protein complex in the rbc membrane. this complex is a tetramer, consisting of two molecules of rhag and two molecules of rh proteins. to express rhd in rbc membrane, expression of rhag is essential. this co-expression only occurs in the erythroid lineage. k562 cell line has an erythroid lineage. materials and methods: cord blood was used ...

objective: dendritic cells (dcs) are essential for the activation and polarization of t cells during an adaptive immune response. in this research we investigated the effect of the lymphoide dcs pulsed with heat-treated tumor lysate (htl) as a vaccine in tumor immunotherapy. materials and methods: the balb/c mice were injected subcutaneously in the right flank with wehi-164 fibrosarcoma cells ...

UNLABELLED The expression of vascular endothelial growth factor (VEGF) under hypoxia in the placenta with intrahepatic cholestasis of pregnancy (ICP) was observed, and mechanisms of ICP fetal distress were discussed. METHODS Different culturing times were established in hypoxia incubator, and protein expressions of VEGF in placental tissue were observed using immunohistochemical S-P method. ...
